Question

A sample of a pure copper has a volume of 3.75cm calculate its mass

Answer 1

Answer: The mass of pure copper is 33.6 grams

Step-by-step explanation:

To calculate mass of a substance, we use the equation:

`\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}`

We are given:

Density of pure copper =
`8.96g/cm^3`

Volume of pure copper =
`3.75cm^3`

Putting values in above equation, we get:

`8.96g/cm^3=\frac{\text{Mass of pure copper}}{3.75cm^3}\\\\\text{Mass of pure copper}=(8.96g/cm^3* 3.75cm^3)=33.6g`

Hence, the mass of pure copper is 33.6 grams
